There are three model variants differing only in the supplied mounting options. All come with a standard waterproof housing (up to 100m), a ‘skeleton’ housing (with holes in it to allow the microphones to record sound) and a range of heavy duty stick or screw on mounting brackets. The ‘outdoor’ pack has a head and flexible strap mounting system for attaching to your dog, yourself or a helmet, the ‘motorsport’ pack has rail and bodywork mounts and the ‘surf’ pack has a strong suction cup for mounting onto a boat, surfboard etc.
